In management research, empirical data are often analyzed using p-value null hypothesis significance testing (pNHST). Here we outline the conceptual and practical advantages of an alternative analysis method: Bayesian model selection Bayes factor. contrast to pNHST, factors allow researchers quantify evidence in favor hypothesis. Also, do not require adjustment for intention with which were collected. The use is demonstrated through extended example hierarchical regression based on design...

Why do people often exhaust unregulated common (shared) natural resources but manage to preserve similar private resources? To answer this question, in study we combine a neurobiological, economic and cognitive modeling approach. Using functional magnetic resonance imaging on 50 participants, show that sharp decrease of is associated with deactivation the ventral striatum, brain region involved valuation outcomes. Across individuals, when facing resource, striatal activity anticorrelated...

Online investing is often facilitated by digital platforms, where the information of peer top performers can be widely accessible and distributed. However, influence such on retail investors' psychology, their trading behaviour potential risks they may prone to poorly understood. We investigate impact upward social comparison risk-taking, activity investor satisfaction using a tailored experiment with 807 experienced investors dynamically evolving simulated stock market, designed...

Many economic theories of decision making assume that people evaluate options independently other available options.However, recent cognitive such as field theory suggest people's evaluations rely on a relative comparison the options' potential consequences subjective value an option critically depends context in which it is presented.To test this prediction, we examined pairwise choices between monetary gambles and varied degree to gambles' outcomes covaried with one another.When by...

Online investing is often facilitated by digital platforms, where the information of peer top performers can be widely accessible and distributed. However, influence such on retail investors’ psychology, their trading behaviour potential risks they may prone to poorly understood. We investigate impact upward social comparison risk-taking, activity investor satisfaction using a tailored experiment with 807 experienced investors dynamically evolving simulated stock market, designed...

Our previous analysis of speaker-adaptive HMM-based speech synthesis methods suggested that there are two possible reasons why average voices can obtain higher subjective scores than any individual adapted voice: 1) model adaptation degrades quality proportionally to the distance 'moved' by transforms, and 2) psychoacoustic effects relating attractiveness voice. This paper is a follow-on from aims separate these out. latest perceptual experiments focus on attractiveness, using...

Abstract To study coordination in complex social systems such as financial markets, the authors introduce a new prediction market set-up that accounts for fundamental uncertainty. Nonetheless, is designed so its total value known, and thus rationality can be evaluated. In two experiments, observe quick consensus emerges early yielding pronounced mispricing, which however does not show standard “bubble-and-crash”. The implemented within xYotta collaborative platform ( https://xyotta.com )....

Recent literature on the intersection of economics, finance and psychology indicates benefits simulated experience in tools measuring decision making. Here, we present Zurich Trading Simulator (ZTS) first used by Andraszewicz et al. (2022) to test impact upward social comparison trading activity. ZTS is a free application for oTree designed create dynamic investment experiments suitable activity risk taking. The software ready-to-use applying default settings. It can also be freely adapted...

Why do people not always choose to take care of the Earth? This study looked at how people’s brains decide nature, like fish in ocean. The scientists made a game that was going fishing, and they used brain-scanning technology see what happening while played. discovered when thought were fishing with other people, took more than alone. brain scan showed part working differently, too. helps us understand work make decisions about nature. If we know our think can find better ways protect...

We propose a new paradigm to study coordination in complex social systems, such as financial markets, that accounts for fundamental uncertainty. This context has features from prediction markets have been shown previously mitigate price bubbles classical asset market experiments. Our setup is more realistic it offers multiple securities are continuously traded over days and, importantly, there no "true" underlying price. Nonetheless, the designed its rationality can be evaluated. Quick...

In financial markets, profit is usually associated with risk-taking, as those who take risks, use the opportunities that markets present. However, during market bubbles, risk-taking might lead to losses, whereas risk aversion can more profit. Emotion-based warning signals play a role here by helping recognize when preferable. To study this, we used trading simulator, where 27 male participants traded on historical stock price trend bubble-and-crash scenario, and continuously monitored their...
